Of course it matters that you signed up, otherwise you have 0 chance to participate to the closed Alpha, nor the tests! Understand that we need to stabilize our game & servers before we make it available to ten of thousands of people, or the experience would be terrible. Time is a friend!

1. There are going to be a lot of monsters, not only chickens
2. The game is going to be an open-world rpg, where we can explore the beautifulness of the nature in Naïca. The last time we were in arena because the devs were testing some things.
3. and 4. I think they haven't said what are we going to test yet.
5. I think it's too early for raids, since there isn't even a party system.
6. I registered too, can't wait to play my second test :3

As Lismo perfectly stated, we will have a certain control over the number of players for the closed Alpha so it will be easier to manage. The number of access is not known at the moment, we will send keys regularly and we do not want 100k+ players coming on day 1 on the servers because they will crash & burn.
